A word of counsel

The most common error on this tariff line is failing to determine upfront whether the specific sulphamide substance is scheduled under the Insecticides Act, 1968 or the NDPS regime — or both — before the consignment is dispatched. Each regime carries its own port restriction and pre-import clearance, and a consignment arriving at an unspecified port without the CIB&RC permit is liable to detention and seizure regardless of whether NDPS documentation is in order. Importers who also trigger the Public Liability Insurance Act, 1991 threshold for specified hazardous substances must arrange the required insurance policy per S.O. 227(E) dated 24-03-1992 before clearance.
